Planting the Seeds of Perimeter
Students will create planters that meet specific perimeter dimensions. The students will need to determine the number of sides and the perimeter for their planter.
Utilize Strip Diagrams to Solve Multistep Multiplication and Division Word Problems
Students will utilize manipulatives to create concrete and pictorial strip diagram representations in order to solve multistep multiplication and division word problems.
Balancing Act
Students use a pan balance model and manipulatives to identify a total that balances two parts. The use of the pan balance will help to develop the concept of equality. Students will develop the language of equality by reading and identifying the following expressions; balances, is the same as, is equal to, and equal before the symbol for equality is introduced. Students will identify an unknown part in a balance situation. Students will communicate ideas, explain, and justify how they solved problems.
The Shapes Around Us
Students will make connections between realworld objects and the attributes of twodimensional shapes.
Centers in Subtraction
Students will participate in multiple centers including a guided math center that reinforces subtraction concepts.
The Picture Graph Party
Students will explore and create picture graphs through collaboration and group work.

Distributive Property
Students break an array apart to represent the sum of two multiplication facts, showing the distributive property.
Texas Essential Knowledge and Skills (TEKS) Related to the Unit
As we looked at the vertical alignment document document available to teachers through the Texas Education Agency and regional TEKS resource pages, it became evident why students struggle with this standard. The skills and knowledge within this standard are not addressed in the second grade TEKS. Students are also required to use multiple skills to correctly calculate the answer using the distributive property. The chosen standard is identified as a third grade readiness standard, which means that the intent is to help students develop a deep understanding of how to effectively use these skills in mathematics. This deep understanding is desired to help students at the fourth grade level since the standard is identified as a supporting standard.

TXRCFP: Texas Response to Curriculum Focal Points for K8 Mathematics Revised 2013
The Texas Response to Curriculum Focal Points Revised 2013 was created from the 2012 revision of the TEKS as a guide for implementation of effective mathematics instruction by identifying critical areas of content at each grade level.
Vertical Alignment Charts for Revised Mathematics TEKS
This resource provides vertical alignment charts for the revised mathematics TEKS.
Representing Whole Number Quantities
This activity provides an opportunity for students to represent whole numbers with pictures.
Determining the Perimeter of a Polygon (Series and Activity 1)
This activity provides an opportunity for students to investigate the perimeter of polygons.
Using Logical Reasoning to Prove Conjectures about Circles
Given conjectures about circles, the student will use deductive reasoning and counterexamples to prove or disprove the conjectures.
Generalizing Geometric Properties of Ratios in Similar Figures
Students will investigate patterns to make conjectures about geometric relationships and apply the definition of similarity, in terms of a dilation, to identify similar figures and their proportional sides and congruent corresponding angles.
Determining Area: Sectors of Circles
Students will use proportional reasoning to develop formulas to determine the area of sectors of circles. Students will then solve problems involving the area of sectors of circles.
Interactive Math Glossary
Making Conjectures About Circles and Segments
Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties and relationships among the resulting segments.
Determining Area: Regular Polygons and Circles
The student will apply the formula for the area of regular polygons to solve problems.
Making Conjectures About Circles and Angles
Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties of and relationships among the resulting angles.
